Protection Board
HYDROFAB MULTIBOARD (Fabricated Dimpled Protection) is a protection sheet flexible composite plastic high-density polymer that is made using high-end technology with 8 mm deep dimples. This excellent quality product is made using a unique process. It is a waterproofing protective membrane, which acts as a critical component for keeping basements dry and also relieves hydrostatic pressure in foundation, thus extending the life of the waterproofing and the foundation structure.
Product Description
Dimple sheets are primarily used for retaining walls to protect waterproofed surfaces from mechanical damage caused during backfilling, as well as from chemicals and harmful gases present in the soil. They act as a protective layer over waterproofing systems in basement foundations and basement floors and are widely used across almost all types of underground structures. The sheets can be installed vertically or horizontally, fixed directly over waterproofing membranes, with adjacent rolls bonded using butt joints and a minimum 50 mm overlap secured by double-sided adhesive tapes.
In addition to protection, they help release hydrostatic water pressure around underground structures and support effective water collection and drainage. These systems are commonly applied under planted podium decks, terrace roof gardens, and deck-roof plazas, and wherever subsoil hydrostatic drainage is required, including basements, lift pits, retaining walls, tunnel surfaces, bridge abutments, and similar structures.
